Abstract
A multi-segment sprocket assembly including a sprocket hub and a multi-segment sprocket. The multi-segment sprocket includes a first partial annular sprocket having a first end that includes a first flange, a second partial annular sprocket having a second end that includes a second flange, and at least a first fastener for releasably securing the first and second partial annular sprockets to the sprocket hub. Also disclosed is a harvester reel including a reel drive mechanism that includes a shaft, and the aforementioned multi-segment sprocket attached to the shaft. Also disclosed is a method for changing speeds of a drive mechanism of for a header of and agricultural harvester. The method includes removing the aforementioned multi-segment sprocket having a first overall diameter from a shaft of the header, and replacing the removed multi-segment sprocket with an aforementioned multi-segment sprocket having a second overall diameter that differs from the first overall diameter.
